In the piece of RFC you're quoting the key word is unicast. I believe
it is quite normal behavior for relay agents to leave unicast packets
between the client and server unmodified. However, I think that you are
getting the DHCPDISCOVER both as the original broadcast from the client
and as a unicast from the relay agent. I don't believe that's normal.
Or maybe it is normal for other products, but at least the relay agents
I use here which are Motorola wireless APs are not behaving that way.
